Fix sharing Agg transition state of DISTINCT or ordered aggs.
If a query contained two aggregates that could share the transition value,
we would correctly collect the input into a tuplesort only once, but
incorrectly run the transition function over the accumulated input twice,

Fix handling of phrase operator removal while removing tsquery stopwords.
The distance of a removed phrase operator should propagate up to a
parent phrase operator if there is one, but this only worked correctly
in left-deep trees. Throwing in a few parentheses confused it completely,

Fix locking problem in _hash_squeezebucket() / _hash_freeovflpage().
A bucket squeeze operation needs to lock each page of the bucket
before releasing the prior page, but the previous coding fumbled the
locking when freeing an overflow page during a bucket squeeze

Fix base backup rate limiting in presence of slow i/o
When source i/o on disk was too slow compared to the rate limiting
specified, the system could end up with a negative value for sleep that
it never got out of, which caused rate limiting to effectively be
turned off.
